Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solid fuel whose main raw materials are coke and oil obtained by steaming O7-sludge, screen scum, and waste tires, and a method for producing the same.

Conventionally, solid fuel using tail tires uses carbon black and ash obtained by incinerating waste tires as the main raw materials, and mixes lignin-containing waste liquid as a binder and kneads the mixture as appropriate. There was one that was granulated to the size of .

But this is a car obtained by incinerating waste tires.]?
Because it is made by mixing black and ash with pulp waste liquid and granulating it, its combustion calorie is low and it cannot generate enough heat to be used as a solid fuel.

The present invention was made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a homogeneous fuel that burns a large amount of calories and is low in cost, and a method for producing the same, using coke and oil obtained by steaming waste tires in a pressure cooker.

Therefore, the solid fuel that achieves the purpose of the present invention is 15 to 3
Contains 5 parts paper sludge, 15 parts to 35 parts screen scum, 69:4% to 25 parts coke, 0.3 parts or more oil, and 15 parts to 0.3% pine tar. It becomes.

The first manufacturing method is to mix 15 to 35% paper sludge and 15 to 35 pieces of screen sludge in a mixer, and then dry it in a drying oven to obtain a dry product. Mixing machine with 69.4% to 25% coke powder obtained by steaming waste tires at 1 pressure, 0.3% oil or more, and 15% to 0.3% pine tar. A mixture is obtained by mixing in a machine, and this is solidified into a certain shape with an extruder or crushed with a crusher #1 to obtain pulverized coal.

The second production method is to mix 15% to 35% of Beichino ξ-sludge, 15% to 35% of screen scum in a mixer, and coke obtained by steaming waste tires in a pressure cooker. Powdered material 69.4% to 25% and oil 0.3%
% or more in a mixer, add dry PK to the mixture, dry it, mix 15% to 0.3% pine resin in a mixer to obtain a mixture, and extrude this into an extruder. It is made into pulverized coal by solidifying it into a certain shape or crushing it with a crusher.

Hereinafter, one embodiment of the present invention will be described using drawings and tables.

iu, penozo - sludge, screen scum, coke, oil, and pine resin were used. This is an example of solid fuel.

Paper sludge is produced directly from paper mills and contains 50% to 95% moisture, preferably 65% to 80% moisture, but this is mixed with 8% to 30% water, preferably 10% moisture. Use dried to ~20 yen. Further, the screen residue is the residue of corrugated plates or the like, or the residue of polypropylene waste paper.

Coke and oil are obtained when waste tires are steamed in a pressure cooker. The temperature for steaming a pressure cooker is 1500'0~23
At 00°C, it is preferably 1700'0 to 2o00°0. Note that the piano wire obtained when steaming waste tires is removed. Further, the coke used is one that is crushed into powder using a crusher. Pine tar is used as a coagulant.

In the table, samples 1, 2, 10, and 17 indicate sample examples outside the scope of the present invention, and samples ① to ① and ＠ to ① indicate preferred solid fuels of the present invention.

Samples 1 and 2 show examples in which either the P/ξ-sludge or the screen scum has a rating of 14. However, in the present invention, it is desirable to have a rating of 15 or more for effective use of this interspecies fuel.

Moreover, if the paper sludge exceeds 35 inches as in Sample 17, the amount of ash after combustion will be large, making it unsuitable as a solid fuel.

On the other hand, the calories burned for sample ■~■+o-0 were also 45
00kcaffl/kg-9500kcaffl/k
It is preferable as a general solid fuel of this type because it can be prayed for until leprosy.

In addition, it is desirable that the amount of screen dregs is the same as the amount of base/e-sludge, <15% to 35%. If it is less than 15%, the burned calories will be low, and if it exceeds 35%, it will be difficult to collect, so this type of solid sludge is ; λ charge and (d unbecoming).

In addition, the upper limit (69.0
Up to about 4 inches, and the lower limit is 25 or more, which is the 11th effect for this type of solid fuel.

Next, the oil content is 0.3% to 7%, but this is required at least 0.3% in relation to the amount of coke, and this kind of oil exceeds Article 44.7. Burns a lot of calories as a fuel! Ru. However, it is not limited to this if the performance of the kettle at the time of delivery is satisfactory.

However, pine tar costs between 15 yen and 0.3 yen, but 0.
．． If it is less than 3%, it will be difficult to solidify as a solid fuel, resulting in cracks, deformation, and cracks, and if it exceeds 15%, it will increase the cost, which is not desirable.

Next, the method for manufacturing solid fuel of the present invention will be explained with reference to the drawings.

(1) First method In the figure, a waste tire 1 is a tire made from waste from own vehicle or other vehicles, and is moved on a conveyor 2 and stored in a pressure cooker 4 via a hono/ξ-3. do. The pressure cooker is heated with burner 5 and steamed with hot air at 1800°C. 6
is the coke outlet. The taken out coke is either in a fluid state or solidified after cooling, and is crushed by a crusher 7 into powder. Reference numeral 8 denotes an oil tank that introduces oil from an oil outlet installed below the pressure cooker 4 and temporarily stores it therein. The oil in the oil tank 8 is led to the mixer 13 as a raw material, and part of it is used as fuel for the i-in-5, and a part of the oil is used as fuel for the melting process using the drying oven 12.

Paper sludge 9 with a moisture content of 60% to 70% is put into a mixer 11 together with screen waste 10 and mixed. The mixture mixed in this mixer 11 is then dried in a drying oven 12 to form a mixture with a moisture content of about 10 to 20 cents. In the mixer 13, the coke pulverized in the pulverized step 7, the oil led from the oil tank 8, the paper sludge and screen scum dried in the drying oven 12, and the pine needle 14 are put and mixed. Ru.

In addition, when using the paper sludge 9 that has been dried in advance, the sludge 9 and the screen sludge 10 may be directly mixed into the mixer 13 as shown by the dotted line.

The Jiff L extrusion molding machine 15 is a screw-type 11" extrusion molding machine that mixes ti, 4; obtain. Further, the crusher 18 crushes the mixture from the mixer 13 to obtain pulverized coal 19.

(2) Second method The second method is almost the same as the first method, but in the figure, the Pξ-sludge 9 and the screen sludge 10 are placed in the drying oven 12 and dried in the mixer 11. In this case, both the coke crushed by the crusher 7 and the coke from the oil tank 8 mixed in the mixer 17 are added. The thus obtained dried product is mixed with pine tar in a mixer 13, and the extrusion mixture is extruded into pulverized charcoal using a shredder.

By the way, the main course is basically 1R page...? - It is a solid fuel in which sludge and screen residue are mixed with coke and oil obtained by steaming B≦ tires, and pine resin is added to this mixture, and this is extruded or made into pulverized coal. To this extent, the timing of adding paper sludge, screen scum, coke, oil, and pine tar may be considered at any other point and is not limited to the above two methods.

In this way, the solid fuel of the present invention includes P-ξ-sludge,
Mix the coke obtained by steaming the tires with the screen residue, and add 100 g of tar to it to create the following effect.

■, Effective for disposing of waste tires (1]-1)
5' can also be reused as a material.

■Coke and oil obtained by steaming waste tires produce 8000 kcE4/J~10(1) Ok when burned alone.
・Since the calorific value of the cone J can be obtained, it is possible to produce a low-cost solid prefuel with a preferable combustion calorie depending on the desired mixing ratio with the paper sludge and screen scum.
